To all whom it may concern:

Be it own that I, JULIAN B. STRAUSS, a citizen of the United States, residing at New Orleans ,in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Mixing Apparatus; and I do hereby declare the following to be a full, clear, and exact descri tion of the inven tion, such as will enable 0t ers skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in. mixing apparatus; and its object is to pro-- duce a simple .a paratus which will dehver into a bag. or other receptacle a mixture of diflerent-materials, the ercentage of each material being accurate y determined and the materials beingthoroughly mixed together by passing through the apparatus.

The apparatus is prnnarily designed for the mixing together of diflerent ,kinds ofgrain, either in its natural condition or crushed, such as corn or meal, rice, wheat, barley, oats,

capable of general a plication. Diflerent grades and varieties of ample, maybe mixed together, diflerent grades of coifee, sugar, salt, mortar, and concrete, and in fact any granular or pulveru lent materials can be mixed together by this ap aratus.

. ith the objects stated view In invention consists'in the construction an combinations of parts, as hereinafter described and claimed. 1 p

In the accompanying drawings, Figure 1 is a. front elevation of my invention with the J'front part of the casing removed. Fig. 2 is a side view thereof. I Fi 3 is a perspective v ew of one of the smal valves or gates, and Fig. 4\-1s a detail view illustrating the construction of the bag-holding part of the device. v

0, represents a casing'or' shell which is divided y partitions 12 into bins c. The partitions, except the central one, are: inclined toward each other, forming comparatively narrow discharge-orifices at the lower ends of the bms, which orifices are located4directly over a contracted throat'd, the partitions I; extending through said throat. Each bin is closed,

at its-{bottom by a gate or valve e, one of which 1s shown in perspective in Fig. 3. Each of-these valves is provided with'a curved 'handle f and on its upper face is provided with ascalemo thatby moving the valve out outer surface of the upper cone.

crushed ore, for ex-' any suitable means. roughly approximates a double hourlass in to one of the divisions of the scale the amount of grain or other material delivered from the corresponding binmay be accurately fixed.

The bottom of the throat d is completely closed by a gate or valve g, which is o erated by an angle-lever h,pivoted in a brac et'i on the casing, and which lever is connected to the valve or gate 9 by a link j. movement of the lower end of the lever h toward the casing will withdraw the valve 'g.

Located centrally below the valve 9 are a series of deflecting-cones 7c, two being shown Obviously the in the drawings; but of course any desired above the top of the lower cone k and thelower one being substantially in line with the n represents a similar series of parallel deflectors on the other side of the casing. I have shown two of these deflectors on each side of the casing but it is obvious that any desired number may be used. Below the throat d the casing is expanded outwardly, as shown at 0, forming a figure in the she; e of a truncated cone .in cross-section, and t e deflectors m and n are preferably arranged parallel to thesides of the casing.

, Below the deflectors m and n the casing is contracted, as shownv at p, which delivers into a sack-holder g, which is fastened thereto by shape as viewed from the front. Wit 'n the contracted ortion p of the casing and araLllel to the sides thereof" are a series of efiec tors r r and s 8, arranged, respectively, arallel to the part 10 of the casing. These efiec tors are arranged to catch the materials delivered from the deflectors m m and n n, re-

outer one of said deflectors extending up The whole casing spectively; but, as shown on the drawings, t e lower series of deflectors is arranged a little farther out than the up er series of deflectors in order to catch and thoroughly mix the streams of material falling down. sired number of deflectors 1' r and s .9 ma be used; but each of the internal deflectors o the lower series is provided with projections t t, arranged to throw the material against the Any de material falling down in proximity to the opposite deflector.

'The lower part of the apparatus is provrded w1th a sack-holding device. The part which is in the shape of a truncated cone, 4

as a rim u on its lower edge, and above that nected to blocks to and 2c, the latter being slotted to receive a pin 'y on the block 10.

2 represents a handle pivoted in the block a; and provided with an eccentric Z. Obviously the rotation of the handle 2 will move the block w along the block 90, tightening the mouth of the sack around the rim u.

The operation is as follows: The bins c, or some of them, being wholly or 'artially'filled with the materials which it is esired to mix together, one or more of the valves or gates e are withdrawn, the scale on each of said valves serving to fix the proportion delivered from each bin. The lever h is then operated, and the materials in the throat d are dis cha-rged into the lower part of the casing, fall:

ing upon the cones 7c, by which they are de fiected, and the princi al part of the material passes in the form of s eet cones onto the deectors m and n, the finer and lighter parts of the mater al, however, falling toward the center. After sliding down the deflectors m and 'n the material carried thereby is caught by the deflectors 1* and s and thrown toward the center, the result being that the materials as they fall through the ap aratus are thoroughly mixed together when. they are delivered into the sack and that a mixture is formed whose percentage is accurately known. 'Of course the sack could be dis. pensed with and the mixed material delivered into any other kind of a receptacle, if desired. Having thus described my invention, what I claim as new, and desire to secure by Let- 'ters Patent, is

1. In a mixing apparatus, the combination of a casing, a narrow throat into which said casing-delivers, a series of partitions passing in presence of two witnesses.

through said casing and through said throat dividing said easing into a number of bins and dividing said throat into a number of small compartments, a series of graduated valves located in the upper art or said throat, one in each of said chamhers, a larger valve adapted to entirely close the lower part of said throat, means for operating said larger valve and means located below said throat for causing the materials under treatment to move back and forth and become thoroughly mixed together as they fall, substantially as described.

2. In a mixing apparatus, the combination of a casing provided with artitions dividing it into a series of bins, sai casing being also provided with a narrow throat into which each of said bins delivers, a graduated valve for each of said bins, said valves being located in the up er part of said throat, a larger valve for a l of said bins located in the lower part of said throat, and means for causing the materials as they fall after leaving said throat to become thoroughly mixed, said means including a series of deflectingcones, a series of parallel diverging-deflectors arranged at a lower level than said cones and a series of converging arallel deflectors arranged below and outside of said first-named deflectors, the inner deflectors of the lower series being rovided with portions projecting toward uh stantially as described.
